§22A-2-34. Misfires of explosives.
(a) Where misfires occur with electric detonators, a waiting
period of at least five minutes shall elapse before anyone
returns to the shot. After such failure, the blasting cable
shall be disconnected from the source of power and the battery
ends short-circuited before electric connections are examined.

(b) Explosives shall be removed by firing a separate charge
at least two feet away from and parallel to the misfired charge
or by washing the stemming and the charge from the borehole with
water, or by inserting and firing a new primer after the stemming
has been washed out.

(c) A careful search of the working place, and, if
necessary, of the coal after it reaches the tipple shall be made
after blasting a misfired hole, to recover any undetonated
explosive.

(d) The handling of a misfired shot shall be under the
direct supervision of the mine foreman or a certified person
designated by him.
